, STEAM-SUPERHEATER.

'vania,ha.ve invented certain new and useful Im rovements in Steani-Superheaters; and I o hereby declare the following to be a full, clear, and exact desbription of the invention', such'aswill' enable other yskilled in the 'art to which itiappertains to make and use the. same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification. '5 My invention relates to steam-super-hat ers and has for its'object the combining of a super-heater with ahorizontal tubular steam boiler in such a manner that a portion of the products of combustion may be deflected from the combustion chamber, and before they have passed through, the boiler fines into the super-heating vdhamber, and, in

carrying out theobject otimy invention to so i locate the point of defieo on. that the prodnets of combustion from the combustion chamber will not-be :so intense as to burn out ,the super-heater tubes.

lhe features of my invention are. hereinafter set forth and fully explained, and are illustrated-in the accompanying drawings, in which: E y i Figure-1, is a vertical central section of the boiler setting and super-heater chamber walls showing a steam boiler and superheater apparatus mounted there n according "to my invention. Fig. .2, is a transverse sec tion of the same, on the line ai- -w, in Fig. 1.

struction in the setting of tubular boi ers of the type I shown in Fig. 1. Transversely I construct a super-heater chamber G, in which chamber I place a super-heating apparatus'l). Through-the rear wall 4& of the heat-chamber A I make an opening G", into the super-heater-chamber C. From the rovide a sm ol e-fiue E, whichis connected 0 the breeching B, by means of a fiue E..

mechanism 1), and the smoke-flue E, is also provided with ,a damper mechanism e. In the super-heater-chamber 'C', I preferably place battle-walls c, and 0, the baffle-wall 0, extending upwardly from the bottom ofthe chamber C, toward the upper portion thereof and the wall 0', extending upwardly from the bottom of the chamber C, to the top.0 of said chambenC, and having an opening 0, in the lower part thereof.

In operation, when it is desired to usel the super-heater-D, the damper'e, in the flue E, is opened, which permits a portion of the heated gas in the heat-chamber A to be drawn through the opening G, into the chamber C, and upwardly over the upper end of the bathe-wall c, and downwardly into the fines E, and E, to'the breeching B and thence to the. smoke-stack. 7

It will be obvious that the amount of heat as may be desired by means of the dampers b, and 6., v

' Having thus fully described and illus tratcd my invention, what I claim as new and desire to secure by Letters Patent is The combination in an apparatus of the character described, of a' horizontal tubular boiler, a furnace thereunder to receive fuel to be burned, a transverse fire-wall, a wall adjacent tothe rear end of said boiler having an opehing therethrough below the up- Ihe'dra'ft-flue B is provided with a damper taken into the chamber C, can be regulated connected with the smoke-stack (notshown), wlnch parts are of usual and ordinar conacross the rear end of the heat-chamber: A,

upper end of this super-heriter-chdmber Q, I

through the opening a", and then upwardly combustion chamber at the rear end of said tubular boiler, vertical side and end walls forming a chamber against said rear Wall,

a drum secured and inclosed Within the, up-

per portion of said chamber, super-heater tubes secured in the shell of said drum and depending therefrom, and a draft flue leading from said'chamber abovesaiddrum,

substantially as set fQrth.

In testimony whereof I afi x my signature in presence of two witnesses.
